RUI: Testing and Characterization of Cryogenic Magnetic Shielding for Photomultiplier Tubes at Liquid Argon Temperatures, and Preparation for Photomultiplier Tube Deployment in the

该奖项为明尼苏达州圣玛丽大学的两名本科生提供设备资金和夏季支持，在2010-2012年的每个夏季为期十周，他们将从事（a）测试大型磁屏蔽的新方法，MicroBooNE中直径为8英寸的光电倍增管（PMT）（Fermilab E974）探测器，将在Fermilab的助推中微子束（BNB）线中运行的液氩时间投影室（LArTPC）;以及（B）参数化屏蔽管性能特性（定时、增益、角响应等）。在安装之前和在检测器中原位。更广泛的影响包括为本科生提供一个非凡的和重点突出的物理研究经验，作为一个正在进行的实验的一部分，在一个主要的国家实验室工作，以及使Nienaber教授与本科生一起工作，准备中微子物理外展会谈，学生可以提供给成员的圣玛丽大学和更广泛的威诺纳，MN社区。预计该项目将对圣玛丽物理系主要课程的本科研究部分的实力产生直接影响，并将间接提高参与学生为现代物理，量子力学和高年级实验室课程做出贡献的能力。

This award provides equipment funds and summer support for two undergraduate students from Saint Mary's University of Minnesota for ten weeks in each of the summers of 2010-2012, to be engaged (a) in testing a new approach to magnetic shielding for large (eight-inch) diameter photomultiplier tubes (PMTs) in the MicroBooNE (Fermilab E974) detector, a liquid argon time projection chamber (LArTPC) that will run in the Booster Neutrino Beam (BNB) line at Fermilab; and (b) in parameterizing shielded tube performance characteristics (timing, gain, angular response, etc.) prior to installation and in situ in the detector. The broader impact includes providing an extraordinary and well-focused physics research experience for undergraduate students to work as part of an ongoing experiment at a major national laboratory as well as enabling Professor Nienaber to work with the undergraduate students to prepare neutrino physics outreach talks that the students can deliver to members of the Saint Mary's University and wider Winona, MN communities. It is anticipated that this project would have direct impact on the strength of the undergraduate research component of Saint Mary's Physics Department's major programs, and would indirectly improve participating students' ability to contribute to department offerings in modern physics, quantum mechanics, and upper-division laboratory courses.
